Best Distribuition for DRBD Deployment

Hello everyone,

I am new on the forum and have a newbie question.
What is the easiest distribution for a DRBD+iSCSI Multipathing+Heartbeat
Single-Primary deployment:

Open SUSE ?
Debian GNU/Linux ?
CentOS ?
Ubuntu Linux ?

Thanks in advance,
Pedro Mazzoni

Hi Pedro,

Asking for "best distro" is always risky and fraught with more opinion
than facts. The most important question is; What is your experience with
the various distros and what are your primary concerns.

I can't answer your question, but I can tell you how I answered mine
and perhaps that will help.

1. Being familiar with both rpm and deb distros left me feeling
comfortable on most distros. So familiarity wasn't a concern. What was
instead though was; Where are the apps I am most interested in being
developed? This was Fedora/RHEL, so I decided on an RPM distro.

2. My highest priority was stability, security and long life-cycles.
This eliminated all "workstation" distros like Fedora and Ubuntu (yes, I
know Ubuntu has an LTS but as I said, I'd already settled on an RPM
release). This meant RHEL, CentOS or Scientific Linux.

With CentOS being designed for binary compatibility with RHEL, I
decided on CentOS as it would give me a fully Red Hat supported platform
for customers with the budgets for timely security patches and a
near-identical free platform for customers with less of a budget.

Further, Linbit, the company behind DRBD, has a support agreement with
Red Hat, meaning that my DRBD-backed projects also had a direct path to
fully paid support.

As I said; You need to answer similar questions yourself. Everyone has
their preferences and will suggest you use the same, but this isn't
ideal as their reasoning is unlikely to match yours.

Cheers

Part of my reasoning was that CentOS is free of cost, but leaves you the
option of going to a fully supported install with minimal hassle.

Re: Best Distribuition for DRBD Deployment [In reply to]

Thinking on hardware compatibility too for many SAN environment and
many FC cards, I chose CEntOS and everything goes perfectly around
DRBD, not only itself

Re: Best Distribuition for DRBD Deployment [In reply to]

Well, to all of you fans of RHEL and derivatives: starting on version
6, it is no longer part of the distro (paid add-on to RHEL): you will
have to use unofficial repositories in order to get drbd (on CentOS /
Scientific Linux), on RHEL, you would have to buy the add-on. I'm not
against paying people for their work (RHEL is good, and they deserve
the payment for their effort), but I just don't use to handle
customers with enough money to pay RHEL + HA plugin.... I donate to
projects when I can, however.

For me, I would use either Debian or Ubuntu server LTS (even with
shorter support term, I prefer Debian, but is just a personal
preference).

Actually, with RHEL you buy your entitlement for the OS from RedHat and support for DRBD from Linbit. You can get the supported binaries for RHEL from Linbit at that point, and RedHat/Linbit will work support cases together which involve DRBD.

None of the RHEL 6 Add-ons get you DRBD. HA just gives you cman/rgmanager/etc. I think even pacemaker is still tech preview as of 6.2.

Ya, you get a linbit repository so installing and updating DRBD is the
same as updating the system itself.
